摘要：
The reception side can easily acquire at least function enhancement information inside a codec.
Image data of each picture of a base layer is encoded to generate a first encoded stream, and image data of each picture of an enhanced layer is encoded to generate a second encoded stream. The first encoded stream and the second encoded stream are transmitted. Function enhancement information including at least function enhancement information inside a codec is transmitted outside the encoded stream. For example, the function enhancement information further includes function enhancement information outside the codec.
